Bitcoin

Bitcoin is a decentralized, anonymous electronic currency that first came into being in 2009. It's still not clear how far Bitcoin can go in establising itself in the mainstream economy, but there are quite a few large and small businesses accepting Bitcoin as a means to purchase goods and services. You can use the cryptocoin to buy produce at a farmers market, security services from major internet companies, as well as drugs and weapons from your favorite online black market. The list of Bitcoin vendors is growing every day.
